Organic acid disorders are rare inherited metabolic disorders of key metabolic pathways. For the identification of specific organic acids, investigation of urinary metabolites and genetic testing are required through newborn screening programmes. Delayed diagnosis leads to complications, such as cardiac attacks, respiratory problems, neuro-developmental disorders, intellectual disability, and even premature death. The burden of such inherited disorders is quite high in developing countries of South Asia due to high rate of consanguinity in the region. Unfortunately, such disorders are left untreated due to the lack of screening facilities in such countries. The current narrative review was planned to highlight the urgent need for closing this gap and implementing effective newborn screening programmes for organic acid disorders in developing countries. The implementation of effective programmes is crucial for reducing morbidity and mortality, and for improving the quality of life for the affected children and of their families, thus promoting global health equity.

Objective: To investigate the association of genetic variants of renin angiotensin aldosterone system, endothelial nitric oxide synthase and 11-beta-hydroxylase genes, and the drug efficacy of angiotensin-converting enzyme inhibitor and angiotensin receptor blocker., Methods: This two time-point study was conducted from April to November 2016 at Allied Hospital, Faisalabad and National Institute for Biotechnology and Genetic Engineering (NIBGE), Faisalabad, and comprised of hypertensive patients taking angiotensin-converting enzyme inhibitor and angiotensin receptor blocker who were followed up for 12 weeks. Baseline and follow-up clinical and biochemical parameters were measured for all patients. Total 11 polymorphisms were genotyped by polymerase chain reaction, polymerase chain reaction-restriction fragment length polymorphism and amplification-refractory mutation system-polymerase chain reaction assays. Data was divided into baseline and follow-up groups, while the latter group was further divided into responding and non-responding subgroups on the basis of patient response to angiotensin-converting enzyme inhibitor and angiotensin receptor blocker drugs. Data was analysed using SPSS 20., Results: Of the 45 patients, 25(55.5%) were females and 20(44.5%) were males. There was a significant reduction in the systolic blood pressure (p=0.004) and low-density lipoprotein cholesterol (p<0.001) from the baseline to the follow-up. Systolic blood pressure was significantly reduced in the responding group (p=0.003), while diastolic blood pressure (p=0.121) was not significantly different. There was no effect of angiotensin-converting enzyme, angiotensinogen, 11-beta-hydroxylase, aldosterone synthase and endothelial nitric oxide synthase gene polymorphisms on angiotensin converting enzyme inhibitor and angiotensin receptor blocker efficacy., Conclusions: Inter-individual response to angiotensin converting enzyme inhibitor and angiotensin receptor blocker was found to be independent of genetic polymorphisms in renin angiotensin aldosterone system, endothelial nitric oxide synthase and 11-beta-hydroxylase genes.

Objective: To investigate a correlation between serum alkaline phosphatase level and body mass index in human subjects., Methods: The comparative cross-sectional study was carried out at the National Institute for Biotechnology and Genetic Engineering, Faisalabad, Pakistan, from April 2012 to June 2013. Blood serum alkaline phosphatase levels were estimated and the subjects were divided into three sub-groups on the basis of their body mass., Index: normal weight (<25kg/m2), overweight (25-27kg/m2) and obese (>27kg/m2) subjects. The serum samples were used for the estimation of clinically important biochemical parameters, using commercial kits on clinical chemistry analyser., Results: Of the 197 subjects, 97(49%) were obese and 100(51%) were non-obese. The serum alkaline phosphatase level increased in obese (214±6.4 IU/L) compared to the non-obese subjects (184.5±5 IU/L). Furthermore, a significant linear relationship (r=0.3;p-0.0001) was found between serum alkaline phosphatase and body mass index. Other biochemical variables were not correlated to the body mass index., Conclusions: Over activity and higher amounts of alkaline phosphatase were linked to the development of obesity.

Adiponectin has been associated with common metabolic disorders. The current study was conducted to measure and compare levels of adiponectin with obesity, type 2 diabetes mellitus (T2DM) and gender in Punjabi subjects from Faisalabad, Pakistan. Serum adiponectin was measured by enzyme-linked immunosorbent assay (ELISA) along with measurements of some clinically important analytes (fasting blood glucose, cholesterol, triglycerides) as well as body mass index (BMI) in 80 subjects. The main results were significantly (p < 0.003) decreased serum adiponectin level in T2DM patients (n = 40) compared to non-diabetic controls (n = 40). In obese subjects, (n = 40) also, there was a decrease, but it was not significant. Adiponectin levels in the subgroups of diabetic and obese patients were also observed, but no significant gender-based differences were found.
